One of my six-year-old cats got really sick after their distemper shots, is this something normal or should I be worried?

Last night, after my six-year-old cat received his distemper shots, he seemed to become quite sick. He’s been unusually lethargic and doesn’t seem interested in his dinner, which is odd for him. Is it common for cats to feel unwell after vaccinations, or should I be concerned about these symptoms?

Answer

It is not uncommon for cats to experience mild side effects such as lethargy or appetite changes after vaccinations, including the distemper shot. While these symptoms are usually temporary, it's important to monitor your cat's condition closely.

  • Monitor for any worsening symptoms
  • Ensure your cat stays hydrated
  • Contact a vet if symptoms persist beyond 24 hours

Vaccinations work by stimulating your cat's immune system to protect against disease, and this process can sometimes cause short-term reactions like lethargy or mild fever. Most side effects are not serious and resolve on their own within a day or two. However, if your cat appears very unwell, stops eating altogether, or if symptoms persist beyond 24 hours, it is a good idea to reach out to your veterinarian for advice.
